3 Claims. (Cl. 20-48) This invention relates to windows. Moreparticularly, the invention is a window including an inner,pane-supporting frame hinged to swing inwardly of the building tofacilitate cleaning.

Conventional windows, whether of the double hung, casement, or someother type, are difficult to clean since the pane is mounted in a framethat either swings outwardly of the building, or is slidablehorizontally or vertically. Due to these conventional arrangements, onecleaning a window from inside the building must place himself in anuncomfortable, inconvenient, and in fact a precarious position, seatedon the sill with half his body outside the window.

In eliminating this deficiency in conventional window design, thepresent invention includes an outer sash frame, shiftable in the mannerof conventional frames between open and closed positions, and an innerframe carrying the pane and hinged to the outer frame to swing inwardlyof the building structure. One is thus enabled to clean opposite facesof the pane from inside the house, without inconvenience, discomfort, ordanger, and without shifting of the outer frame from its normal, closedposition. An object of importance is to not only facilitate the cleaningof the window, but also permit the improved window to be mounted in aconventional window frame without modification of said window frame. Theimproved window can thus be used as a substitute for windows already inuse.

Another object is to secure the above noted advantages without materialincrease in the cost'of manufacture of the window.

A further object is to obtain the desired results without detractingfrom the appearance of the window.

Yet another object is to provide, in association with the outer andinner sash frames, sealing strips carried thereby capable of beingcompressed when the inner frame is closed to prevent vibration of theinner frame and to further prevent leakage or drafts between thecontacting surfaces of the inner and outer sash frames.

A further object is to so design the sealing strips as to eliminate theneed for puttying the window pane in place.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a front elevational view of a window formed in accordance withthe present invention, seen from within the building.

Fig. 2 is a vertical sectional view on line 2-2 of Fig. 1, on anenlarged scale.

Fig. 3 is a detail sectional view, still further enlarged, on line 33 ofFig. l.

Fig. 4 is a detail sectional view, on an enlargedscale,

rates Patent 2,776,459 Patented Jan. 8, 1957 on line 4-4 of Fig. 1,showing the lock of the inner sash frame member.

Fig. 5 is a sectional view, still further enlarged, on line 55 of Fig.4.

Fig. 6 is an enlarged sectional view, similar to Fig. 4, showing amodified form.

Fig. 7 is a sectional view similar to Fig. 6, but on a scale stillfurther enlarged, the inner frame being closed.

Fig. 8 is a fragmentary perspective view of the modified inner frame.

The reference numeral 10 designates a building wall, having a windowopening in which is fixedly mounted a rectangular Window frame 12including side jambs 14, a header l6, and a bottom piece 18. A sill 20projects interiorly of the building in coplanar relation to bottom piece18, and an apron 22 depends from the sill in contact with the innersurface of the room wall. All this is conventional and does not per seconstitute the invention. However, it is of importance that the improvedwindow constituting the invention is mountable in a wholly conventionalframe 12 already in use, merely by removal of the conventional sashesand substitution of the improved sashes for those removed.

Lower and upper sashes formed in accordance with the invention have beendesignated generally at 24, 26, respectively. In the illustratedexample, a double hung window is shown. However, the invention can beembodied in any type of window in general use, including casement,horizontal sliding, reversible, awning, austral, and basement windows.In every instance the sash, regardless of how it is mounted in thewindow frame for movement between open and closed positions, and even iffixedly mounted in a permanently closed position, includes an outer sashframe, and an inner, pane-carrying sash frame movable inwardly of thebuilding structure between open and closed positions relative to theouter sash frame.

In the illustrated example, since the window is of the double hung type,there is a parting strip or bead 28, and side strips 3% extendingvertically on the inner surfaces of the side jambs, to provide adjacent,vertical trackways for the lower and upper sash frames 24, 26.

Since the frames 24, 26 are identical, only the frame 24 will bedescribed.

The sash frame 24 includes an outer or main sash frame member 34 ofrectangular formation, the outer surfaces of the side rails of which areslidably engaged in the associated vertical trackways of the windowframe 12. The inner periphery of outer frame member 34 is formed with acontinuous rabbet groove 36 of right angle cross section, and mounted inthe rabbet groove is an inner sash frame member 38 also of rectangularformation, and also having, on its inner periphery, a continuous rabbetgroove 40. A window pane 42 is mounted in the rabbet groove 40, and isputtied in place as at 44.

The inner frame member 38 is hinged to one side rail of the outer sashframe member 34 by hinges 43. These may be conventional butt hinges asshown in Fig. 3. It is of importance that the hinging of the inner framemember 38 is such as to cause said member to swing inwardly of the room,between an open position, and a closed position shown in Fig. 2. Whenthe inner member is swung inwardly, the outer and inner surfaces of thepane 42 can be cleaned, from inside the room, by one standing or seatedin the room in a comfortable position. The outer sash frame member 34,of course, need not be shifted from its normal position in the windowframe if desired.

Means to lock the inner member 38 in normally closed position is shownin Figs. 4 and 5, and includes a rotatable shank mounted in that siderail of the inner member opposite that to which hinges 41 are connected.The

shank is integral or otherwise made rigid at its outer end with a knob46 accessible from inside the room to rotate the shank. The inner end ofthe shank has a reduced projection 48 of noncircular cross section,extending axially of the shank and engaging in a complementarily shapedopening-formed in the inner end of a locking arm 58 of blade-likeformation. Arm 56 extends radially of the locking shank, and in theclosed, locked position of the inner frame member the outer end of thearm engages in a locking recess 52 formed in the adjacent surface offrame member 34. The inner end of arm Si) is in a recess 54 of the innermember 38, the recesses 52, 54 communicating in the closed position ofthe inner frame member and having arcuate inner walls merging into oneanother as shown in Fig. 5.

To open the inner frame member, knob 46 is rotated 90 to shift the arm54) to a position in which it is confined entirely within recess 54.

In the modification of Figs. 6-8, the modified sash 24 includes an outerframe member 34* having a rabbet groove 36 on its inner periphery. Oneside of the rabbet groove is closed by an overhang or ledge 56, andengaged in the rabbet groove is a soft rubber sealing strip 58 ofL-shaped cross section, the outer surfaces of said sealing strip beingperpendicular to one another and being seated H against theperpendicularly related walls of the rabbet groove.

Formed in the sealing strip 58 is a slit 60 which normally is slightlyopen (Fig. 6) at its outer edge to impart a tapered cross sectionalshape thereto. The inner edge of the slit terminates in spaced relationto the point of intersection of the perpendicularly related outersurfaces of the sealing strip. The slit 60 lies in a plane passingthrough said point of intersection and bisecting the right angle definedby the outer surfaces of the sealing strip.

The slit 6b opens upon the inner surface of the sealing strip. As shownin Fig. 6, normally the sealing strip has the inner surface portions 62,64, defined at opposite sides of the slit 60, disposed at an obtuseangle to one another, so that the sealing strip can be said to be formedwith perpendicularly related legs bisected by the slit, with each legbeing thickest immediately adjacent the slit and decreasing in thicknessin the direction of its outer longitudinal edge.

A sealing strip 66, also of soft rubber or other readily compresible,resilient material, is applied to the inner sash member 38*, and extendsthrough the full periphery of said inner sash member. Inner sash member38 has a rabbet groove th receiving pane 42, the sealing strip 66 exte-ding as an overhang adjacent the groove to hold the pane in plane.Thus, no putty is used in the modied form. instead, strip 66, at spacedlocations throughout its periphery, has transverse, counterbored,smoothwalled openings 68, reeciving a leg screw 70, threaded into thesash member 38 Sealing strip 66 is formed with obtusely related outersurfaces 72, '74, surface 74 engaging against surface por tion 6d andsurface 72 engaging against surface portion 62.

When the inner sash member 33 is in an open position (Fig. 6), strips58, odexpand. When, however, sash member 33 is swung to closed position,pressure is eX- erted against surfaces '72, 7d inwardly thereof, tocompress the 'o 6-6 and form the surfaces 72, 74 into perpendicult. 1,related surfaces (Fig. 7). Surfaces 72, 74, meanwhile exert pressureagainst the surfaces 62, 64, forcing them inwardly so that they alsoassume a perpendicular relationship. Slit 6i) closes under thecompressing action exerted against strip 53. As a result, a very tightseal is provided between the inner and outer sash members 33 34*,respectively, to. prevent leakage, vibration, or drafts. Further, thearrangement .se-. curely holds the window pane inplace without putty,and it will benoted that in the closed position of the inner sashmember, the edge of the window pane is encased securely-in the sash, soas to be prevented from dropping out. The pane is securely held in placeby the compressed strips, and it will be noted that the pane isprevented from moving out of its rabbet groove 48 not only by thesealing strips, but also by the outer sash member, which backs up thecompressed sealing strips in the area through which the pane would moveif it where to tend to drop out of the rabbet groove 40 When the innersash member is closed, of course, the window functions in the samemanner as any conventional window, the outer sash member being shiftedupwardly or downwardly in the illustrated example to open or close thewindow as the case may be. Further, the invention could be embodied inany other type of window, and in each instance, when the inner sashmember is swung to closed position, the outer sash member can be openedor closed in the regular manner.

Further, the invention can be substituted for conventional windowsashes. In the illustrated example, it may be noted, it would benecessary only to remove the guide strips 23, Stl, 32, to take out theold sashes and substitute the new ones.

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claims.
